Land Rover Repair: FREELANDER TD4 2003, crankshaft sensor, amp fuse
Freelander starter rel  
ANSWER: Hi Malcolm,

could be camshaft or crankshaft sensor failure too.  If either of these sensors fail you will not be able to start the engine.

Starter relay in engine compartment, 2nd row of square relays, top relay.  Will try to attach a pic...

if not, send me and email and I'll send you the page.

Best of luck,

QUESTION: is there not a relay just for the glow plugs when i turn the key to num 2 dut not to turn engine over there is no power to the plug that fits onto the glow plug.
the glow plug do work as i have tested them out of the engine
thanks malcolm

Answer
Hi Malcolm,

perhaps this will help:

<<Starting
Main Relay
The earth path for the main relay coil (C0576) is controlled by the Engine Control Module
(ECM) (C0603) on a WK wire. The energised main relay provides a feed to fuse 1 which is
also located in the engine compartment fuse box. Fuse 1 (C0576) provides a feed to the
glow plug relay (C0215) on an RW wire.

Glow Plug Relay
Fuse 6 of the passenger compartment fuse box (C0581) provides an ignition feed to the
ECM (C0603) on a W wire. If all criteria are met, the ECM (C0606) provides an earth path
for the glow plug relay coil (C0215) on a BR wire.
Fusible link 6 of the engine compartment fuse box (C0577) provides a constant battery feed
to the glow plug relay switch (C0215) on an NW wire. When the relay is energised, the switch
contacts close, allowing the glow plug relay to provide a feed to the following:
 To glow plug number 1 (C0476) on a BG wire.
 To glow plug number 2 (C0477) on a BP wire.
 To glow plug number 3 (C0478) on a BY wire.
 To glow plug number 4 (C0479) on a BR wire. >>

No power to glow plug could be caused by an number of things: the ECU is not working, a sensor failure is preventing the ECU to provide power, the ignition switch is not working, relay failure, link failure.  Did you know that the coolant temp sensor failure could also cause this, as would a weak battery.

I've been told that a common problem is the ignition switch itself.  Have you tested this out?

Best of luck,
JohnMc
